The Ford Fiesta ST 2013 1.6 Ecoboost-SCTi package is a fully programmable replacement for the factory fitted ECU in Ford Fiesta ST models.

This product is designed primarily as an engine control system and may not fully integrate with all OE systems. In particular the starting, fuel supply, and alternator systems' operation may differ and require modifications to vehicle wiring. Refer to the Operation section of this document for details.

  • Pre-configured CAN messaging for OE systems including ABS / VSC, dashboard and power steering.
  • Configurable control of OE coolant fan with temperature thresholds.
  • Pre-configured transient fuelling compensation using physical modelling of fuel film for direct injectors.

  • Gearbox position detection via sensor or engine speed / wheel speed.
  • Gearbox shift request via up shift switch / down shift switch or gear lever force sensor.
  • Gearbox shift control with ignition cut and engine speed matching.

  • Engine Load Average channel with tables for engine speed limit, ignition timing trim, fuel mixture aim, boost limit, and throttle limit.
  • Engine run time total for engine hour logging.
  • Configurable security for multiple users with differing access options.
  • ECU CAN Receive from a defined ID base address for data reception from MoTeC devices.
  • 6 configurable driver switches, 4 rotary switches and 4 CAN switches each with 9 positions that can be simultaneously mapped to launch control, pit switch, anti-lag, traction, race time reset, engine speed limit maximum, throttle pedal translation, fuel volume trim, ignition timing, fuel mixture aim, boost limit, traction aim, and traction control range.
  • Pulsed tachometer output with configurable output pin and scaling.
  • Transmission pump output with transmission temperature threshold and hysteresis control.

When the M142 ECU is installed according to the included wiring pinout, this package mimics most aspects of OE operation as follows.

Start System

The OE vehicle utilises either a conventional ignition key or an immobiliser key fob to control power supply to the ECU and to crank the engine. The M142 package does not interact with the OE starting system, so modification to the OE wiring harness may be required if the package is not used with a purpose-built wiring harness for racing applications.

Air Conditioner

A function group is provided for direct wiring to air conditioner components, including refrigerant pressure sensor and air conditioner compressor clutch. Enable conditions cater for multiple choices including throttle position, engine speed, and temperatures. For these functions to be available the vehicle wiring may need to be modified, and inputs and outputs defined.

Power Steering

No user interaction or settings are required.

ABS / Stability

While this product uses some sensor information provided by these systems (for example wheel speeds) no further interaction occurs.

Accelerator Pedal

Ford Fiesta OE systems use a pedal with two outputs: a pulse width output which is wired direct to the ECU, and a voltage output which is wired to the IPC (instrument panel cluster), and then transmitted to the ECU via CAN messaging. The M142 solution requires both signals to be wired directly to the ECU as detailed in the included pinouts.

As many racing applications make use of pedal boxes with two voltage outputs, this is also catered for in the package. Refer to help content in the Throttle Pedal Sensor group of the package.

Coolant Shutoff and Coolant Bypass

Ford 1.6 SCTi engines have a shutoff valve and a bypass valve which may be used to alter cooling system behaviour. Settings for these devices are found in the Ford Fiesta ST Coolant Shutoff and Ford Fiesta ST Coolant Bypass groups of the M1 package.

Turbocharger Wastegate and Bypass

Ford 1.6 SCTi engines have a conventional wastegate solenoid and a compressor bypass valve. Settings for the wastegate are found in the Boost group, while settings for the bypass are found in the Turbocharger Bypass group of the M1 package.

Low Pressure Fuel Pump (Lift Pump)

Ford Fiesta ST vehicles control the low pressure fuel pump (lift pump) via an FPDM (Fuel Pump Driver Module). This device is not controlled in this package, so a normal low pressure pump and relay should be substituted.

Power Relays

Ford Fiesta ST vehicles control the PCM relay from the ECU. When the M142 ECU is installed according to the included wiring pinout, these outputs may be configured from the ECU Power Relay group of the M1 package.

Some variants of the vehicle may control these relays independently, so actual behaviour may not always match the settings in the M1.
